Carbon cycle PERIOD 3

2.
Natural Process
Ñ Carbon enters the atmosphere as carbon dioxide from
respiration and combustion.
Ñ Carbon dioxide is absorbed by producers to
make carbohydrates in photosynthesis.
Ñ Animals feed on the plant passing the carbon
compounds along the food chain. Most of the carbon
they consume is exhaled as carbon dioxide formed
during respiration. The animals and plants
eventually die.
Ñ The dead organisms are eaten by decomposers and
the carbon in their bodies is returned to the
atmosphere as carbon dioxide. In some conditions
decomposition is blocked. The plant and animal
material may then be available as fossil fuel in the
future for combustion

5.
Ñ All living things are made up of
carbon
Ñ Without it all living things would die
Ñ Without carbon dioxide, plants
wouldn’t be able to go through
photosynthesis and release oxygen
Ñ Carbon is found in the atmosphere,
along with other gases. These gases
keep the earth warm.
Importance

6.
Ñ Burn fossil fuels which releases CO2 into the
atmosphere. Ex. Oil, natural gas, and coal
Ñ Deforestation
Ñ MDC: Russia (one of the largest oil producers) and
China (the largest coal producers)
Ñ LDC: Indonesia (6th largest producers of fossil fuels)
and Iran (one of the largest producers of natural gas)
Ñ Due to all the excess CO2 release from burning fossil
fuels and deforestation, the Earth is geVing warmer
causing Global Climate Change.
